小学数学教学中转化思想的运用(国外英文资料) The application of transformation thought in primary school mathematics teaching This article source: paper / Abstract transformation is an important thinking method in solving mathematical problems. The transformation of ideas is an important basic thought in analyzing and solving problems. Many mathematical ideas are the embodiment of transforming ideas. Keywords primary school; mathematics teaching; transformation; Thoughts on solving the essence, which means that the problem solving transformation, strange problem into the familiar problem, the abstract problem is transformed into a specific problem, the complex problem is transformed into a simple problem, the problem is transformed into a special problem, the problem is transformed into a higher bottom problem, the unknown conditions into a known condition a comprehensive problem into several basic problems, put forward thinking into reverse thinking. Therefore, in primary school mathematics teaching, we should combine the specific teaching content, infiltration of mathematical transformation thinking, consciously train students to learn to use transform ideas to solve problems, so as to improve mathematical ability. First, analyzing the transformation of primary school mathematics knowledge structure from the angle of transformation is one of the most basic methods in primary school mathematics thinking method. In depth analysis of the transformation ideas in primary school mathematics textbooks, we can better grasp the knowledge structure of teaching materials, and help to improve the efficiency of classroom teaching. The following combination of their own teaching practice, from the transformation point of view to analyze primary school mathematics content: (1) calculation. 1. vertical transformation of calculation. Addition and subtraction: 20 - the number of addition and subtraction within 100 less than the number of the number of addition and subtraction, addition and subtraction
